ADAS Calibration in Phoenix, AZ

The Hohokam people occupied the Phoenix area for 2,000 years. They created roughly 135 miles (217 kilometers) of irrigation canals, making the desert land arable, and paths of these canals were used for the Arizona Canal, Central Arizona Project Canal, and the Hayden-Rhodes Aqueduct. They also carried out extensive trade with the nearby Ancient Puebloans, Mogollon, and Sinagua, as well as with the more distant Mesoamerican civilizations. It is believed periods of drought and severe floods between 1300 and 1450 led to the Hohokam civilization’s abandonment of the area.

After the departure of the Hohokam, groups of Akimel O’odham (commonly known as Pima), Tohono O’odham, and Maricopa tribes began to use the area, as well as segments of the Yavapai and Apache. The O’odham were offshoots of the Sobaipuri tribe, who in turn were thought to be the descendants of the Hohokam.

The Akimel O’odham were the major group in the area. They lived in small villages with well-defined irrigation systems that spread over the Gila River Valley, from Florence in the east to the Estrellas in the west. Their crops included corn, beans, and squash for food as well as cotton and tobacco. They banded with the Maricopa for protection against incursions by the Yuma and Apache tribes. The Maricopa are part of the larger Yuma people; however, they migrated east from the lower Colorado and Gila Rivers in the early 1800s, when they began to be enemies with other Yuma tribes, settling among the existing communities of the Akimel O’odham.
